Printrbot Simple Ribbon Cable Brackets

I love my Printrbot Simple, but I kept getting shorts and breaks in the wires running to the extruder because of all the cyclic bending. These brackets mount D-Sub connectors at the Printrboard and at the extruder, so you can connect the two with a ribbon cable. No more taking apart the wire bundle to find the break. If the ribbon cable wears out, just plug in a new one.
